I'm doing a mission where you need to go from Pearl to Hokkaido and engage merchants. I've got my boat to Japanese waters now and met a convoy there. I started encountering it but... After I had used all my 4 fore tubes (and waited about 15 minutes after it) I was wondering why the tube 1 has 4%/100% reload, I checked crew management and found out..
My all crew members where fatigued 94-98/100 O____o I never actually use the all crew to battle stations and I didn't have it on now either, both 1st and 3rd "row" of the crew had that said huge fatigue and second had nothing.
So yeah, let's try to win a war with a crew like this.....
